At 12 years old, Kiernan Shipka (Sally Draper) seems to be sailing quite smoothly into the treacherous waters of puberty. Props to her parents/stylist for helping her maintain her sweetness during this difficult transition.

Jessica Paré (Megan Clavert) was simple but still interesting in her LBD.

John Slattery (Roger Sterling) and Jon Hamm (Don Draper) were dapper while Robert Morse (Bertram Cooper) seems to be at peace with his choice of corduroys and sneakers.

Jennifer Westfeldt was gorgeous in emerald green. I loved how Embeth Davidtz's (Rebecca Pryce) gown was at once modest and sexy. However, I'm not feeling costume designer Janie Bryant's gown.

Carla Ortiz is not on this show (as far as IMDb is concerned) but she needed to be included in this roundup simply because of her mindfuck of a belt.
